'18 G80 sport AWD here....I've had mine installed for over 2 years now and I'd say, I'm making ~17mpg 50/50 city/highway and ~22mpg highway, on ~1500 round trip doing 75+mph.

Ok. Better question, since I have a g70. How much mpg did you lose?

Idk, ~2mpg? but it feels good to have ~450hp/480tq under the hood ;)
